, FLUSH VALVE.

Application filed June 28,

T 0 all whom it may concern:

Be it known that I, HENRY W. SOHWAB, a citizen of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Flush Valves, of which the following is a specification.

This invention relates to flush valves and has for its pri11 -ioal object to provide a valve of this nature which when once open *ill remain open until the water in the tank or receptacle in which the valve is located has completely flowed therefrom.

Another object of the invention is to generally improve upon flush valves of this character by providing a device which will be of extremely simple. durable and inexpensive construction, one which is efiicient and reliable in operation, and well adapted 'to the purpose for which it is designed.

lVith these and Illlll'lGXOllS other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawing Figure l is an elevational view of the flush valve,

Figure 2 is a vertical section taken through the lower portion thereof, and

Figure 3 is a plan view of the dipper used in conjunction with the valve.

Referring to the drawing in detail it will be seen that l designates the body of the valve which is provided with the threaded shank :2 so as to be supported in a tank in the usual manner. This shank 2 acts as the outlet of the valve. The body 1 is provided with a valve seat 3 and a neck 4;. An overflow tube 5 is threadedly mounted in the neck 4 and extends upwardly therefrom. The valve consists of the weight element 6 and washer element 7 which rests normally upon the valve seat 3. A shank 8 extends upwardly from the weight element 6 and passes through a guide 9 carried by the bracket 1 which is suitably supported on the tube 5.

A. bracket 11 is suitably fixed to the top of the tube 5 and. a rocker arm 12 is pivoted thereto intermediate its ends. This rocker consists of a straight portion 13 and an offset portion 14. The straight portion is connected to the shank 8 by means of the rod 15. A rod 16 is connected to the offset portion 1a and depends therefrom so as to extend through the overflow tube 5 and ten Specification of Letters Patent.

minate adjacent the bottom of the body 1 of the valve. A dipper 1.7 is attached to the rod 16 so as to be situated in the upper portioirof the shank or outlet 2. This dip per 1s provided with a plurality of perforat ons so as to allow any water caught therein to drain therefrom.

In operation any suitable means (not shown) is used for lifting the shank 8 so as to disengage the valve washer element 7 from engagement with the seat 3 thus allowing the water to pass through the body of the valve. As the water passes there through it will be seen that the dipper will have taken a position shown in dotted lines in Figure 2 and that the water flowing through the shank 2 or outlet will engage the dipper l7 and the force of this water will hold the valve in an open position through the intermediary of the dipper l7, rod 16, rocker arm 12, and rod 15. This valve will remain in an open position until all the water in the tank has flowed therefrom at which time the weight element 6 will return the valve to a closed position. It will also be noted that should there be considerable overflow passing through the tube 5 this overflow would engage the dip per 17 and should it become excessive would tend to lift the valve from engagement with the valve seat As numerous changes in form. proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention. 1. do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is In combination, a flush valve comprising a valve proper, a rocker arm fulcrumed above the valve. .1 rod attached to one end of the rocker arm, a dipper situated in the body portion of the valve and arranged to receive the force of the water when the valve is open, said dipper being rigidly mounted on said rod and supported thereby, and a second rod attached to the other end of said rocker arm and attached to the valve proper.

In testimony whereof I allix my signature in presence of two witnesses.

HENRY W. SCHWAB.
